Well, we're still trying to understand mechanism. Again, we're at the observational level that's really indisputable. Because these bacteria, there's what we call nitrate-reducing bacteria. And humans do not have this enzyme. So nitrate is what's found in green leafy vegetables, right? These plants assimilate nitrogen in the soil in the form of nitrate. We consume these vegetables.
The nitrate is taken up in the gut. It's concentrated in our salivary glands. And the bacteria... perform this metabolism of nitrate into nitrite and nitric oxide. And humans do not have the functional enzyme to do this. We're 100% dependent upon the bacteria.
So then now, because nitrate is inert in humans, we rely on the bacteria to metabolize this molecule into a usable form where we can make nitric oxide. So when you're killing the bacteria, now the nitrate is just being recirculated, but you're urinating because it's filtered across the kidneys. You poop it out and you sweat it out. So it's completely unchanged unless you have the right bacteria.
And what we're finding is that that oral production of nitrite and nitric oxide being produced in the acid environment of the stomach is somehow regulating resistance arteries in dilation to normalize systemic blood pressure.
As it relates, there are many benefits of many nutrients in foods, particular plants, that confer some health benefits. But when we focus specifically on the benefits of nitric oxide from your diet, if you don't have the right oral bacteria, you get zero nitric oxide benefits from your diet.
Now, you're going to get, you know, obviously, hopefully vitamin A, vitamin C, vitamin D from foods, fiber, other phytonutrients. But in terms of the blood pressure lowering effects of, for instance, a plant-based diet, if you don't have the right bacteria, you get zero benefits of that.
Yes, absolutely.
People that have dental infections, root canals, cavitations from previous extraction sites, have typically cancer. It sets the stage for cancer cell growth and proliferation. So I made a controversial statement on a previous podcast where I say, number one, I'm not an oncologist.
But people who have terminal metastatic disease who aren't ready to die, who are sent home to die on hospice, somehow find me and go, can you help me with this cancer? So the first thing I always send them to is a dentist. to see do you have any active oral infections that may have led to the development of the primary tumor in the first place.
But obviously it's metastatic, meaning that it's now everywhere. It's migrated outside that primary tumor. But almost always without fail, they have an active oral infection. And it may be a symptomatic infection to where they know it and they have a toothache, or it may be an asymptomatic infection where they don't even know they've got a dental infection.
People with primary tumors, solid tumors, so we categorize these in blood-borne cancers, something like lymphoma, leukemia, multiple myeloma, which is a blood-borne cancer, and those that have a solid tumor, a primary tumor that starts in the breast, the colon, the prostate, the lungs, or the liver. Without fail, 100% of them have dental infections.
Cause and effect, no, I don't think we're there yet. I think probably as the science advances and people start to look at this. Because you may imagine...
If you have cancer and you've been to the best cancer doctors in the world and you've done surgery, you've done chemo, you've done radiation, you've gone through the standard of care and the cancer comes back, it's terminal, it's metastatic, and you tell, when I tell people, well, you need to go see a dentist. I mean, many people laugh and they go, what in the hell did you just say?
I've got cancer. I don't have a dental problem. And I go, well, perhaps you do. Because again, if you go back, and I always look back, what's held true throughout ages? And if you look at Ayurvedic medicine, if you look at traditional Chinese medicine, if you look at acupuncture, and if you go back and you look, if you don't know what to look for, you're never going to find it.
If you know what to look for, it's out there. It's in the published literature. But every tooth in the body is connected to an organ system, right? And so these are the meridians, the acupuncture meridians. You know, the analogy is they're circuit breakers. So if you trip a breaker in your home, there's no electricity going through that circuit.
So your oven doesn't work, your refrigerator doesn't work, your lights go out. Well, the body is electric, right? And how do we diagnose death? No electrical activity, right? Either through an EKG or an EEG. So the body is electric and we're batteries. And so if that red light comes on on our phone, it says we have a low battery, everybody panics and goes and plugs it in and charges, right?
And the human body is the exact same. We lose voltage over time. And if you've got a trip breaker from an infected tooth, there's no voltage, there's no circuitry going to that meridian that feeds individual organs. So the best example is if you've got a root canal, and 100% of root canal teeth are infected. And when you think about it, people go, well, that's not true.
Well, think about what a root canal is. You had a toothache at some point because of an infection. So you go to the dentist and they pull the nerve root out of that tooth. So you don't feel the pain anymore because there's no nerve root there. And they pull the blood supply out of that tooth. Now you have no blood supply to that tooth. And a tooth is a crystalline structure. It's a living organ.
With no blood supply and no nerve root, that's a dead tissue. So if you were to go in and we'd disconnect your gallbladder, for example, and just cut the blood supply to it, the nerve supply to it, within seven or 10 days, you'd be dead from sepsis. Nobody leaves dead tissue in the body. And so then what happens is when you leave the dentist, what do they do? They put you on an oral antibiotic.
But they must have forgotten they took out the blood supply to that infected site. So an oral antibiotic isn't going to reach the site of infection. I mean, to me, when you sit back and think about this and go, who the hell does this and why do they do it? Well, it's because of what we've always done. So then what happens is these anaerobic bacteria, they don't need oxygen.
